Split Systems
A split system simply means your solution has products that reside both inside and outside your home. In many cases, a split system consists of:
- Furnaceâprovides heating and the fan used year round to circulate air
- Evaporator coilâthe indoor component of your outdoor cooling unit
- Air conditioner or heat pumpâworks in tandem with the evaporator coil
- Ductsâcarry the conditioned air throughout your home
- Control or thermostatâyour interface for controlling your system
- Optional air quality accessoriesâclean, humidify, and freshen air before it circulates throughout your home
Some split systems consist only of an outdoor unitâsuch as a heat pump or air conditionerâand an inside fan coil. If thatâs the case, thereâs usually another heat source in the home like baseboard heat or a boiler.
Heat Pump Split Systems / Hybrid Heat Âź
Itâs a smarter version of your standard split system, with an energy efficient twist: In addition to gas furnace heat, this system automatically figures out how to get the best efficiency by also using an electricity-fueled heat pump to provide warmth. Bonusâthe heat pump functions in the place of an air conditioner too.
In the warmer, humid climates of the south you might consider a high performance heat pump with a lower efficiency and lower up front cost furnace so you can have the furnace as backup heating on really cold nights, while taking advantage of the high-efficiency heat pump most of the year. A heat pump with a variable-speed compressor matched to a furnace with a variable-speed blower motor can do an amazing job of pulling humidity out of the air in the summer to save money.
Meanwhile, in colder climates, itâs best to pair your heat pump with a high-efficiency furnace. Despite the cold, you might be surprised by just how much mileageânot to mention cost-saving efficiencyâyouâll get from a heat pump in the spring, fall and, yes, even winter months.
A Hybrid Heat system includes:
- Heat pumpâprovides summer cooling and dehumidification and warmth in cooler seasons
- Evaporator coilâthe indoor component of your outdoor heat pump
- Furnaceâprovides heating and the fan used year round to circulate air
- Ductsâcarry the conditioned air throughout your home
- Control or thermostatâyour interface for controlling your system
- Optional air quality accessoriesâclean, humidify, and freshen air before it circulates throughout your home
Ductless Split Systems
As you may have guessed from its name, a ductless split system doesnât rely on air ducts to spread treated air in your home. Instead, this specialty system is designed to heat or cool room additions or other places that may lack ductwork, such as home theatres, exercise rooms, garages or any other area where the existing system doesnât quite cut it. Ductless split systems include:
- Small outdoor air conditioner or heat pump unit
- A compact indoor wall unit
- Refrigerant tubing and wire connectionsâpass through a small hole from indoor to outdoor unit to connect the system.
- On unit or remote controlâyour interface for controlling your system
Packaged Systems
Some homes just donât have space inside for a furnace or the coil needed for cooling. That doesnât mean they canât be filled with the same comfort and improved air quality of a split system home.
Packaged units tend to all look alike but can do vastly different things:
- Cool only as an air conditioner
- Cool and heat as an electric heat pump
- Cool and heat as a Hybrid HeatÂź dual fuel system of gas furnace with electric heat pump
- Cool and heat as a gas furnace with electric air conditioner
As an all-in-one unit, the only other thing you need is a control or thermostat and, of course, ductwork to carry the conditioned air. Additionally you can add air quality accessories if you like. Packaged systems may be located on the exterior of your home, either on a flat rooftop or in the yard.
Geothermal Heat Pump Systems
Traditional heat pumps do the same thing as air conditioners but in winter, they do it in reverse, drawing their heat energy from the outside air. Geothermal heat pumps don’t have to rely on the potentially wide temperature swings of outdoor air. They tap into the relatively consistent and more moderate temperatures of the earth instead. Using your yard, pond or well water, this ingenious technology enables you to enjoy higher energy efficiency inside your homeâno matter how extreme the weather gets outside.
There are geothermal systems that can serve homes with ductwork or homes with radiant heat. The radiant heat versions are referred to as hydronic systems and some of those can also provide you with all your hot water needs.
A geothermal system can be used to provide all of your heating and cooling needs or you can pair it with a furnace for a dual fuel heating solution.
